Thank you, jeremyspouken!
Works like a charm for me now aswell when I deactivated WooCommerce which made me the Products CPT.
I think something just went wrong when I updated the plugin through the WordPress admin panel..
Now I just deleted the plugin and reinstalled it and deactivated all the functions that were using simple_fields_register_field_group(); so I could reactivate the new version and then it worked.
Why do I have to do it this way?
